Thanks everyone for your help and I got it to work again by reverting back to prior Wyze app version 3.18.0.918.
Wyze Thermostat Not Loading After App 3.19.0 Update — Fixed on Android 16
I had an issue where my Wyze Thermostat stopped loading in the Wyze Android app after updating to version 3.19.0.
I’m using Android 16. The physical thermostat continued working normally and all my other Wyze devices were working in the app.
I tried with no luck:
Clearing the Wyze app cache
Rebooting my phone
Rebooting the thermostat
Rebooting my router
Using cellular data instead of Wi-Fi
Unistall and reinstall app with latest version.
Tested:
Used another Android device will older version Wyze app and thermostat loaded ok. This verified that the issue was related to recent release version of app with android 16.
What fixed it:
I rolled the Wyze Android app back to version 3.18.0.918.
Wyze’s official release notes show 3.18.0.918 was released July 23, 2026.
I downloaded the unmodified Wyze 3.18.0.918 APK bundle from APKMirror. The package was:
com.hualai
Wyze Labs Inc.
Version 3.18.0.918
Because it was an .apkm bundle, I used APKMirror Installer to install it.
After installing 3.18.0.918 and signing back into the same Wyze account, the Thermostat loaded normally again.
Important
I did not:
Factory-reset the thermostat
Remove/re-add the thermostat
Delete any cameras or other Wyze devices
Delete my Wyze account
Good news:
My automations, schedules, cameras, plugs, and other devices remained associated with my account.
So, on my Android 16 phone, rolling back from Wyze 3.19.0 to 3.18.0.918 fixed the thermostat loading problem.
Hopefully this helps anyone else experiencing the same issue after the 3.19.0 update.
WYZE: It would be beneficial to make the previous version readily accessible for individuals experiencing difficulties. I encountered considerable trouble researching and locating an official prior version. I was reluctant to install the Wyze app from an unofficial source, but I had no alternative as I required remote control of my thermostat via the Wyze app.
Please share if your having issue with the thermostat after this update.
